using the formula: n=m/gfm
no. of moles=mass/gfm
you take the gram formula mass (gfm) as 4.
and given the mass is 16g, both numbers can be substituted into the formula...
n=16/4
= 4
the number of moles present in 16g of helium is 4 moles.
4,0 moles of the manganese contain 219,75 g.
The number of moles is mass in g/molar mass in g.
Sc is a s block element. There are 1.16 molesin 52.3 grams.
Well, one mole is 26.98 g, right? Your ten grams is thus (10/26.98) moles.
To determine how many moles of octane are present in 16.0 g, you would divide the mass of octane by its molar mass. The molar mass of octane (C8H18) is approximately 114.23 g/mol. Therefore, 16.0 g ÷ 114.23 g/mol = 0.14 moles of octane.
156 g calcium is equivalent to 3,89 moles.
4,0 moles of the manganese contain 219,75 g.
4,0 moles of the manganese contain 219,75 g.
To determine the number of moles of sulfur in a 16-g sample, you need to divide the mass by the molar mass of sulfur. The molar mass of sulfur is approximately 32 g/mol. Thus, 16 g/32 g/mol = 0.5 moles of sulfur in the sample.
To find the number of moles in 0.289 g of methane, first calculate the molar mass of methane (CH4), which is approximately 16 g/mol. Next, divide the given mass (0.289 g) by the molar mass to obtain the number of moles. Therefore, 0.289 g of methane is equivalent to 0.289 g / 16 g/mol ≈ 0.018 moles of methane.
The number of moles is mass in g/molar mass in g.
0.515 moles
moles H = 0.3086 H x 1 mol/1 g = 0.3086 moles Hmoles P = 3.161 g x 1 mol/31 g = 0.101 moles Pmoles O = 6.541 g x 1 mol/16 g = 0.41 moles Odivide all by 0.101 to get 3.0 moles H, 1 mole P and 4 moles OEmpirical formula = H3PO4
To find the number of moles in 16 g of oxygen gas, you need to divide the given mass by the molar mass of oxygen. The molar mass of oxygen (O2) is 32 g/mol. Therefore, 16 g / 32 g/mol = 0.5 moles of oxygen gas.
25 moles of sulfur dioxide contain 600 grams of oxygen. Each mole of SO2 contains 2 moles of oxygen, and the molar mass of O is 16 g/mol. So, 25 moles x 2 moles = 50 moles of O, which is 50 moles x 16 g/mol = 800 g of O.
Sc is a s block element. There are 1.16 molesin 52.3 grams.
Well, one mole is 26.98 g, right? Your ten grams is thus (10/26.98) moles.
